toas ers,

,applica To ail whom itmay concern in the county of Ross and State Baiubridge, of one i have invented certain new ant useful Improvements in Elevating lrucks for Vehicles, of which the following is a specification. v

My invention relates to elevating trucks'fl for vehicles and is particularly designed to provide a -:forrn of truck primarily ap plicahle'to motor vehicles and designed to provide a traveling structure of such form thatthe vehicle carried thereby, may be readily elevated for the purpose of maintaining its Wheels out or contact with the ground. This is particularly desirable in the storage of motor vehicles having cushion or pneumatic tires, since the removal 0 these tires from contact with the floor or ground, tends to preserve them and lengthen their life. in the provision of a means to attain this end, my aim has been to provide a structure which will be extremelypractical owing to its inherent simplicity ant which Will, at the same time, completely fulfil all of the requirements of a device 51' this type.

lvicre specificall my invention takes the form of: a base structure with casters thereon to render it readily movable and a super-- structure connected to said base structure by vertical adjusting means of such term that 'a simultaneously vertical movement of all PGlIliZSOf the superstructure may be attained' icy the rotation of a single crank Furthermore, there is provided a. means for readily obtaining the correct tenelements.

Referring specifically v I ers of retcrence in which similar charact designate corresponding parts: Figure 1 is a top plan view of my trunk, Fig. 2 is vertical longitudinal section 3 is end elevation, and, Fig. l is detail view of the elevating screw,

The'hase structure of my device is oreferably comprised of two transverse anemhaving downward extensions outward extensions 5 and 6 and bent extremities 'Z S; The extremities 7 and 8 are, respectively, connected together by longitudinally,inclined hard-hoards fiend 10 having their ends wine-d by cross piece lland: The out- :tvard extensions 5 g 3 and at,

sprocket 27 is then rotated by means of its crank or by the hand grips thereon and such rotation causes the sprocket chain 26 to drive the sprockets l8 and feed the rod 25 to elevate the said super-structure and consequently the vehicle. 'W hen this is done, the truck may be Wheeled to any point because of the casters 13 and let.

The provision of the inclined longitudinal boards 9 and 10 upon. the sides of my truck, is of importance for the reason that ii it practically insures a proper positioning of the vehicle over the truck. Primarily they serve the purpose of maintaining the v knuckle joints and steering connections to the Wheels in their proper position relative to the superstructure. hen running an automobile onto my truck, the operator Will steer the same by gaging its Widest part to clear the same. Should he, however, not accurately gage it, the fore part of the Wheel Will strike the upper portion of the inclined side and Will then necessarily swing the truck into its proper position. This is inevitable, for the reason that the Wheels will first contact with the upper portion of the inclined boards and it the alinement is not exactly correct, they slide thereon in a manner calculated to move the truck into its proper position. Furthermore, the legs of the truck are guarded against contact by the Wheels of the vehicle. Thus there is no danger of a vehicle wheel striking a leg of the truck and looking therein as devices.

It Will be apparent from the above, that a simple structure has been devised which Will at all times maintain the vehicle/With its Wheels removed from contact with the oor or ground and vhich at the same time will provide a ready tion of the vehicle from point to point. I

What I claim, is

A portable elevating truck for vehicles comprising transverse base members, downwardly and outwardly inclined side boards carried by longitudinally of the truck, a superstruc ture spanning the distance between said transverse members, gated extensions on the ends of said superstructure, and means for vertically adjusting said superstrueture.

In testimony whereof I afiix my signature in presence of two Witnesses.
